Press CTRL + ALT + DEL, what do you see ? The windows taskmanager with lots of processes, showing a filename like svhost.exe and a memory usage of that process. Besides checking for trojans, spyware and virii: What´s a good way to check for possible causes if your computer behaves slowly ? Right, the taskmanager. Unfortunatly the process don´t give you lot´s of information which application did cause them to run on your windows version.
Windows Process Information will deliver this information to your screen. Just enter the filename (process name) and you will see a short description of the process and what caused it. The entries seem user submitted, it is a good idea to check more than one source if you are unsure if you can safely terminate a process. (processlibrary is such a second site).

What is that file ?

Actually CTRL + ALT + ESC takes you to the Windows Task Manager. CTRL + ALT + DEL takes you to the security dialog. CTRL + ALT + ESC is a great shortcut.
This information is not correct, CTRL + ALT + DEL takes you to the task manager..
whether ctrl+alt+del brings up the task manager directly depends on the version of windows and how the system is configured… certain XP configurations will bring it up directly for ctrl+alt+del but in general for NT based versions of windows it is the ’security dialog’ mentioned above…
really ? I never experienced something else, it was always the taskmanager..
There are many alternatives to task manager but one of best is Sysinternal’s
Process Explorer. You can see what’s running with helpful info about various processes
if you hover your cursor over an entry. You can suspend, kill or google a process
depending on how confident you’re feeling. Best of all, it’s freeware.
